Can someone explain Line Lock to me?

 

What do you want to know? All it is, is an electric solenoid that goes between your master cylinder and then y's out to your front brakes. When you get ready to do a burn out you press down the brake pedal, and while holding the brake pedal you then hold down the activation switch to the solenoid and it "locks" the presserized fluid going to the front calipers, then I, while still holding the button, press the pedal 1 or 2 more times to really build line pressure so the car won't budge. When the tires get hot you release the button and the cars moves again as if you took your foot off the brake pedal. Once guys hook up their 2 or 3 step, they usually install a four wheel line lock to hold the entire car while it's up on the stutter box.

 

Thanks, thats all I really needed...
